Q: Bluetooth audio lag

Problem remains after 10.10.1 upgrade. :-(

I re-paired my bluetooth headsets after the update and that solved the problem for me.

Updated to 10.10.1, audio still lagging. Tried re-pairing my headset but the issue persists. Tried clearing SMC and PRAM, no results.

In the bug report I submitted to Apple, after I provided some BluetoothReport diagnostics they requested, I was told that my report was a duplicate of another issue, so apparently they truly are aware of the problem.

Same here I've cleared PRAM and SMC several times to no avail.  The update did not improve things at all.  I'm beginning to feel like I'm back on my Microsoft Laptop.  I read on some forum that backing up your Mac and then doing a clean install solves the problem, but that is a time consuming process especially without a SSD.

I did everything suggested in this topic, but the audio still lags and stutters. The bluetooth audio receiver works great with my other laptop (Windows) and my iPad, so I'm pretty sure it has something to do with my macbook.

i now did the clean install. Bluetooth lag is STILL there.

this will not fix it, save your time.

looks like i have to do another clean install but this time Mavericks. Thx Apple.

i just bought a BeoPlay A2 B&O.

Audio lags when i watch a QT video from a MBP 2014 13'' updated to 10.10.1. Same thing using my iPhone 6.

Help me Apple guys.

Apple the new Microsoft 

Have the same issue with Logitech bluetooth audio adapter from the moment I've upgraded to Yosemite. The latest update does not fix the problem. I get when the first version has a few bugs, but after this issue was reported by like everyone who's using bluetooth audio and Apple still has failed to recognize it and include a fix in this update... Gee. Very disappointed.

Heres my latest update with the Bluetooth problem.

I did a clean reinstall of Yosemite to wipe any possible conflict from my end of the matter.

The system worked smooth for a few days as I caustially added programs like VLC and didn't use Bluetooth, just plugged-in headphones.

I started to use bluetooth and the lagging problems started again. What's more my memory and CPU problems also started acting up tho I dont know if they're related.
And this was with a clean system i.e. no weird 3rd party applications.

so i erased the harddrive again and did an Internet Recovery process, bringing my late 2012 iMac to Mountain Lion.

I was headed to Mavericks OS and decided to do a quick test of Mountain Lion.

In mountainlion I checked the Activity Monitor and all the processes that were taking up large amounts of memory or CPU usage were gone.

I used iTunes to test the music.

What I noticed was in Mounatin Lion, bluetooth worked.

If I was performing another big process it would clip but it was different kind of sound problem than Yosemite.

While Yosemite, upon these "skips" whether it was the system thinking or a quick break up of connection between comp and external hard drive the sound would skip.

But it would also find its previous place in the song and I suffered no delayed audio just stuttering, which was minimal. Way better than whatever Yosemite was doing. I'd be interested in how bluetooth works. Just before I did a Mountain Lion reinstall, I noticed in the Clean version of Yosemite that upon sound skipping (the point at which the BT headphones would go out of sync and start delay) the headphones could find their proper place again after the skip.

After a delay in audio I would press the pause button and the headphones would "find themselves" again at the last point in the song or video.

Now I'm in Mavericks and I'll try this system. So far i already have 550 mbs dedicated to "kernel task" which is the same as Yosemite. Mountain Lion had no processes this large in the short time I spent with it. I've yet to try Bluetooth with Mavericks but it was definitely a step in the right direction getting out of Yosemite.

My two cents.

I'm with you, readytorun. I have two MacBook Pro 2011 models. One is running Mavericks and the other is Yosemite. Mavericks is great - I rarely have issues. For the life of me, I have no clue why I updated to Yosemite. I can't listen to music or watch video. God forbid I try to do two tasks at the same time. And now, every time my cell phone rings, my **** laptop starts ringing and won't ever stop - even long after the phone call is over. UGH.

OK, I might be jumping the gun, and I don't know what the technical fouls are, but when I have Yosemite installed , for whatever reason, it does not work with my system, even a complete clean system with nothing on it (like possible conflicting 3rd party apps).

I did an internet Recovery, went back to Mountain Lion and upgraded to Mavericks. While my "kernel task" memory remains high, as it should, the CPU percentages which were showing at 300% with the same "kernel task" in Yosemite was ridiculous and left me with a system where I couldn't open even 2 applications. and forget Bluetooth.

So far, after a day of pushing this system (Mavericks) to the limit of what Yosemite, for some reason, just couldn't pull off: VLC movie playing from an external drive source, while downloading a file, playing a 1st person shooter network video game, emptying the trash, listening to iTunes and all on bluetooth...

- and things work fine.

normal cpu percentages, mail works, bluetooth is probemless - the OS just feels solid.

so even if theres still some hat trick I didn't try over the past month with Yosemite - and it does look nice and clean.. right now Mavericks is solid.

It just works.

I agree with readytorun, I was stoked with Mavericks, everything was running so great, I couldn't wait to upgrade and see what Yosemite was capable of... bad move.  I just wish I was technically capable of downgrading to Mavericks, but sadly, I'm not tech-savvy and would probably mess things up royally...

thanks, this decision took over a month to make and, in the end, after accepting that I had an adequate "picture" of the hard drive (having used Time Machine with my external hd) I decided to wipe the drive and the system. Wasn't easy but it was a question of dealing with problems every day or taking the chance it would work.

i restarted while pressing cmd r: the computer shifts into the recovery utility. i went into the disk utilities and chose Erase.

after that i went to the file menu ad restarted my machine. this is a different step than my first time restoring.

the first time i went to the recovery menu after erasing my disk and reinstalled. this reinstalled Yosemite.

the difference on the 2nd time around was, after erasing the hard drive i restarted the machine. it took me to Internet Recovery and then to a similar Recovery utility as before.. this is where the program set up the original OS that came with the computer.. so mine was Mountain Lion.

after it set up and the system was running i went into the app store and downloaded Mavericks from my previous purchases.

hope that keeps it simple, I'm no computer dude either, but most of my questions and problems I was able to look up with Google and read a lot, and from multiple sources. Good Luck, the only constant during [my only] problematic times with this computer were when Yosemite was present, that was the line in the sand for me. Just make sure you know you have everything you want in terms of personal data. so far tho, no problems with Mavericks and great for the daily grind - having a secure system takes away daily anxiety about what process would kill what next. now I can get back to work. smoke weed.

LOL! Now I see where the patience comes from...

Well, all I have is the Time Machine backups, and I'm not even totally sure that's reliable enough in this case. I don't have another harddrive to rely on, so looks like I'm stuck waiting for Apple to do something about the CPU stuff and everything else, all the other quirks (like Facetime ringing whenever I get a regular phone call on my cell at the same time - oy!)

I will keep this post in mind though if I end up freaking out at some point and decide to do the downgrade. Wish it was easier, for sure, but I'm glad it worked out for you. Thanks for your help
